Environmental risk assessment of discharges of sediment during prospecting and exploration for seabed minerals Prepared for Ministry for the Environment

摘要: The Ministry for the Environment (MfE) has identified that more detailed and comprehensive information is needed to fully inform policy decisions relating to the discharge of sediments during prospecting and exploration for seabed minerals. NIWA was engaged by MfE to undertake an assessment of the environmental risk of sediment discharges arising during exploration and prospecting for iron sands on the shelf along the west coast of North Island, phosphorite nodules on the Chatham Rise, and seafloor massive sulphide (SMS) deposits along the Kermadec volcanic arc.
